2.79 Plant response to stimuli

Notes


1. Stimuli = changes in the environment
       - Temperature
       - Light

2. Receptors detect stimuli
    Receptors ----- plant Hormones/growth regulators (e.g. Auxin) -----> Response

3. Response
       - Growth from stimuli = Tropism
          - Temperature    
          - Light                    = Phototropism
          - Gravity                 = Geotropism
          - Water/Moisture     = Hydrotropism
